3. “To be mad is to feel with excruciating intensity the sadness and joy of a time which has not arrived or has already been. And to protect their delicate vision of that other time, madmen will justify their condition with touching loyalty, and surround it with a thousand distractive schemes. These schemes, in turn, drive them deeper and deeper into the darkness and light (which is their mortification and their reward), and confront them with a choice. They may either slacken and fall back, accepting the relief of a rational view and the approval of others, or they may push on, and, by falling, arise. When and if by their unforgivable stubbornness they finally burst through to worlds upon worlds of motionless light, they are no longer called afflicted or insane. They are called saints.” - Mark Helprin

Bush has gathered around him upper-crust C-students who know no history or geography, plus not-so-closeted white supremacists, aka Christians, and plus, most frighteningly, psychopathic personalities, or PPs, the medical term for smart, personable people who have no consciences.To say somebody is a PP is to make a perfectly respectable diagnosis, like saying he or she has appendicitis or athlete's foot . . .PPs are presentable, they know full well the suffering their actions may cause others, but they do not care. They cannot care because they are nuts. They have a screw loose! . . .So many of these heartless PPs now hold big jobs in our federal government, as though they were leaders instead of sick. They have taken charge of communications and the schools, so we might as well be Poland under occupation.They might have felt that taking our country into an endless war was simply something decisive to do. What has allowed so many PPs to rise so high in corporations, and now in government, is that they are so decisive. They are going to do something every fuckin' day and they are not afraid. Unlike normal people, they are never filled with doubts, for the simple reasons that they don't give a fuck what happens next. Simply can't. Do this! Do that! Mobilize the reserves! Privatize the public schools! Attack Iraq! Cut health care! Tap everybody's telephone! Cut taxes on the rich! Build a trillion-dollar missile shield!

Run until your lungs collapse, until the wind whips and snaps at your tattered clothes, until you're a blur that blends into the background. Run, Juliette, run faster, run until your bones break and your shins split and your muscles atrophy and your heart dies because it was always too big for your chest and it beat too fast for too long and you run.Run run run until you can't hear their feet behind you. Run until they drop their fists and their shouts dissolve in the air. Run with your eyes open and your mouth shut and dam the river rushing up behind your eyes. Run, Juliette.Run until you drop dead. Make sure your heart stops before they ever reach you. Before they ever touch you.Run, I said.” - Tahereh Mafi

102. “From around the corner's edge a grotesque light was trickling out, the first intimations of an ominous sunrise over a dark horizon. I dimly recognized this colored light, though not from my waking memory. It grew more intense, now pouring out in weird streams from beyond the solid margin of the building. And the more intense it grew, the more clearly I could hear the screaming voice that had called out to me in a dream. I shouted his name, but the swelling colored brightness was a field of fear which kept me from making any move toward it. It was no amalgam of colors comparable to anything in mortal experience. It was as if all natural colors had been mutated into a painfully lush iridescence by some prism fantastically corrupted in its form; it was a rainbow staining the sky after a poison deluge; it was an aurora painting the darkness with a blaze of insanity, a blaze that did not burn vigorously but shimmered with an insect-jeweled frailness. And, in actuality, it was nothing like these color-filled effusions, which are merely a feeble means of partially fixing a reality uncommunicable to those not initiated to it, a necessary resorting to the makeshift gibberish of the mystic isolated by his experience and left without a language to describe it.("The Dreaming In Nortown")” - Thomas Ligotti
103. “One secret of life is that the reason life works at all is that not everyone in your tribe is nuts on the same day. Another secret is that laughter is carbonated holiness” - Anne Lamott
